avoid writing jshint ignore in blueprint tests if jshint is not detected

[philtobias]

Addresses #117.

This will only output the following line if ember-cli-jshint is detected in the project's add on packages.

/* jshint expr:true */

the <% } %> part should probably be at the beginning of the next line to make sure that we don't have the unnecessary line break at the start of the file

I'm not following. Can you show me an example of what you mean? The following will output the unnecessary line break as well.

<% if (jshintExists) { %>/* jshint expr:true */
<% } %>

[Turbo87]

<% if (jshintExists) { %>/* jshint expr:true */
<% } %>import {
  describe,
  it,
...

this should work afaik

[philtobias]

That works. Thanks for clarifying. I've updated the code.
